Lateral intrasphenoidal encephaloceles are rare anomalies. We describe a unique case in which spontaneous bilateral intrasphenoidal lateral encephaloceles were discovered in a 53-year-old man during a work-up for cerebrospinal fluid leak. We discuss our clinical findings and the results of preoperative computed tomography and magnetic resonance imaging.
